The objectives of the study were to estimate the repeatability of health and welfare traits and investigate their association with performance in three breeds of dairy goats reared under low-input farming systems in Greece. A total of 1210 goats of Eghoria ( = 418), Skopelos ( = 429), and Damascus ( = 363) breeds were assessed. Udder health, parasitic resistance, welfare, milk yield and quality, and body condition score were recorded monthly for two milking periods. Read More

The objective of this scoping review was to describe and characterize the existing literature regarding umbilical health and identify gaps in knowledge. Six databases were searched for studies examining umbilical health in an intensively raised cattle population. There were 4249 articles initially identified; from these, 723 full text articles were then screened, with 150 articles included in the review. Read More

Elephantoloemus indicus Austen, 1930, a dipteran calliphorid fly is known to cause by its larval stage obligatory cutaneous myiasis in Indian subspecies of Asian elephants (Elephas maximus indicus Cuvier, 1798) in Myanmar and Thailand. The present study was undertaken on morphological identification of some specimens of fly larvae which were recovered from the warbles detected on the skin of captive Indian elephants at the Nameri National Park and Kaziranga National Park both situated in the state of Assam, India. The larval specimens were whitish to creamy white in colour and body conformation varied from cylindrical to barrel shaped depending on their measured size (Av 6. Read More

Myiasis refers to infestation of living animals or humans by maggots, or fly larvae. Urogenital myiasis is a rare condition that is linked to poor sanitary conditions and limited access to healthcare and with few published case reports. Here, we describe the case of a sixty-seven year old homeless woman with multiple comorbidities who presented with extensive vaginal myiasis requiring inpatient management with ivermectin, ceftriaxone and metronidazole, and daily larvae extraction and debridement.

Purpose: Human conjunctival myiasis, which is often misdiagnosed or missed clinically, is commonly caused by Oestrus ovis larvae. Here, pathogenic identification was performed for two maggots collected from a patient from China, to provide a clinical scientific basis for diagnosis and treatment.

Methods: Morphological identification was performed using a microscope. Read More

Background: Myiasis is an infection of the tissues and organs occurring in animals or humans by fly larvae, and human ophthalmic myiasis has been described worldwide.

Methods: We report here a rare case of unilateral severe conjunctival ophthalmomyiasis due to the larvae of Oestrus ovis in Jixi city, Shaanxi province of west China, in which the climate is relatively dry and cold.

Results: The larvae were verified as the first instar larvae of Oestrus ovis according to the previously described morphological criteria. Read More

Background: The sheep blowfly, Lucila cuprina, is a myiasis-causing parasite responsible for significant production losses and welfare issues for the Australian sheep industry. Control relies largely on the use of insecticides. The pyrimidine compound, dicyclanil, is the predominant control chemical, although other insecticides are also used, including imidacloprid, ivermectin, cyromazine and spinosad. Read More

Purpose: The tumbu fly, Cordylobia anthropophaga (Diptera: Calliphoridae), is widely distributed in continental tropical and subtropical Africa, being the most common cause of furuncular myiasis in Sub-Saharan Africa. The aim of the present work was to analyze the role of rodents as possible reservoirs of C. anthropophaga in Cape Verde, considering the zoonotic character of this fly species. Read More

Botfly infiltration is a rare cause of pediatric skin manifestations in the United States, but should be considered in nonhealing wounds even in nontravelers. We describe the case of a healthy 6-y-old female who had never traveled outside of the southeast United States, presenting with a nonhealing skin lesion. The point-of-care ultrasound (POCUS) findings suggested subcutaneous parasitic infiltration. Read More

Wohlfahrtia magnifica is a pest fly species, invading livestock in many European, African and Asian countries, and causing heavy agroeconomic losses. In the life cycle of this obligatory parasite, adult flies infect the host by depositing the first-stage larvae into body cavities or open wounds. The feeding larvae cause severe (skin) tissue damage and potentially fatal infections if untreated. Read More

Introduction And Importance: Myiasis has been reported as a complication of fracture treatment with external fixation. Therefore, physicians should be aware of the possible re-emergence of myiasis as a complication of surgery and the use of metal fixators.

Clinical Presentation: A 45-year-old male, non-diabetic, chronic alcoholic treated with external bone fixation and flap coverage for Gustilo-Anderson type IIIB comminuted fracture of shaft of left tibia and fibula with intact distal neuro-vascular system presented with multiple maggots with foul-smelling discharge from the pin tract.

Dermatological cases caused by myiasis make up approximately 20% of travel diseases. Ocular involvement occurred in approximately 5% of these myiasis cases. The conjunctival involvement of () larvae, which is the active agent in most ocular infestation cases in humans, causes external ophthalmomyiasis. Read More

Blowfly strike or cutaneous myiasis, caused principally by the Australian sheep blowfly Lucilia cuprina is endemic to Australian sheep producing areas and is a major cause of suffering and economic loss. This article reports incidence and control practices as determined by three cross-sectional surveys of Australian sheep farmers covering the years 2003 (n = 1365), 2011 (n = 575) and 2018 (n = 354) with more questions relating to blowfly strike in the latter two surveys. Breech strike was reported at a higher rate than body strike in all survey years. Read More

Background: Myiasis, as defined by the Centers for Disease Control and Prevention, is infection with fly larvae commonly occurring in tropical and subtropical areas. Whereas the presentation of skin infection with organisms such as Dermatobia hominis (human botfly) is more easily recognized in these regions, identification of myiasis in the United States is difficult due to its rarity. Due to unspecific signs and symptoms, myiasis may initially be mistaken for other conditions, like cellulitis. Read More

We described a 56-year-old Indonesian man with one-month history of nasal obstruction and rapidly increasing nasal swelling and two weeks history of severe facial pain with foul smelling discharge, bleeding and noticing live maggots emerging from his nasal and oral cavity. On examination, he appeared cachexic with a markedly swollen, erythematous and deformed external nose. Live maggots, pus and necrotic tissues were found in both nasal cavities, with erosion of upper gingiva and hard palate. Read More

Myiasis, infestation of the human body by larva of flies is an under-recognized and ignored medical condition. Not only is this condition unsightly and extremely distressing to the patient, but it also generates a ghastly feeling in care givers and health care workers as well. The authors report extensive myiasis of the leg in a patient with filarial lymphedema from southern India, which is rarely illustrated in published literature. Read More

The New World screwworm, Cochliomyia hominivorax (Coquerel 1858) (Diptera: Calliphoridae), is a serious parasite of livestock, humans, and other warm-blooded animals. It has been eradicated from the northern parts of its historical range down to the Panama-Colombian border where a permanent barrier zone is maintained. This eradication was accomplished through using the sterile insect technique (SIT). Read More

Delusional parasitosis is a psychotic illness. Patients often present to dermatologists with scars that are self-inflicted because they attempt to extract the "parasites". We report a 58 -year-old female with an eight-month history of a crawling sensation on her skin and constant generalized itching, which she believed to be caused by insects and worms crawling across her skin.
